Happy birthday to you
     One birthday won't do
     You must be born again
     And then you'll have two!

When we are born, we become part of a family. And each year we celebrate that day - it's our birthday.
If we ask God to forgive us our sins and ask Jesus in to our lives as our Lord and Saviour, the Bible (God's Word to us), says that we are born into God's family - we are BORN AGAIN.

Well, if we are born AGAIN then each year we can celebrate that day also - it's our spiritual birthday.
